Do you have multiple CRUSH roots or device classes? Are all OSDs the same weight? > My disk sizes differs from 1.6T up to 2.4T. Ah. The number of PG replicas as reported by `ceph osd df` should be proportional to the OSD capacities. With some of your OSDs double the size of others, it is natural that some will have double the number of PGs. That said, 2.4T is an unusual size for a drive. What specific storage drives are you using? Chances are that you’d benefit from bumping pg_num on at least some of your pools. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
